Frequently Asked Questions (FAQs)

1. Should swim trunks be above the knee?

Length. Proportionally and visually, this is what looks best on men and as a basic rule, no matter how tall you are, your trunks should always above the knee by at least 3” above your knee. The length should hit at mid-thigh, at the longest. This proper length will make akes you (and your legs) look longer.

2. What should boys wear for swimming?

Boys can wear swim trunks or even swim briefs or jammers if they like. Try not to let the swim trunks run too long so that it interferes with their kick. Their trunks should stop just above their knees.

3. Why is there netting in boys swim trunks?

The primary purpose of the net inside a pair of swim trunks is to provide support to the genitals while swimming. The netting hugs the genitals close to the body in a manner similar to brief-style underwear. This keeps them out of harm's way during physical activity.

4. Can boys wear swim briefs?

Briefs feature a rounded high-cut leg and were the most popular type of male swimwear in the late 20th century. Swim briefs have a simple design and generally produce the less drag when compared to jammers and trunks. This makes them an excellent choice for young club swimmers or kids in swimming lessons.
